Chapter 3 provides an in-depth analysis of the biological aspect of psychology. The chapter is centered around the structure and function of the human brain. Biological psychologists continue to look for ways in which the nervous system and human behavior are related. As scientists continue to conduct research and experiments, greater knowledge and understanding of the structure and function of the brain becomes available. Undoubtedly, the brain is a very complex organ within the body. As presumed by its great complexity, the brain is one of the most important parts of the body as it is a strong determinant in the way humans perceive the world and then react to certain perceptions.
One of the areas that I found interesting and I would like to highlight is adrenaline. Adrenaline is released from the adrenal glands (shown in picture), many times in very dangerous or exciting situations. High levels of adrenaline within the body trigger changes in which people are sometimes able to perform amazing acts. One example was a woman temporarily obtaining the strength to lift a car to save her trapped infant. This superhuman ability triggered by an adrenaline rush is personally very fascinating.
